[Tagging] noexit=yes on ways ? (a typical OSM story)

This thread is unbelievable. I just goes on and on, endlessly discussing
something that was crystal clear from the moment I first saw that tag. It
is quite obvious that the people who use the tag for ways either did not
read the Wiki or misinterpreted the use of the tag (as we've discussed *ad
nauseum*) and tagged ways because they thought there should be a warning,
like a sign, at the start of the dead-end way rather than at the end.

I don't know about QA tools but for me, it means I do not have to do any
more investigation of that highway — it ends where the NODE IS TAGGED with
noexit. The end node that's tagged is the last one — the drawing of the way
stops there. What other "end" is there?

Thanks for the clarification of the Wiki, whomever did it. I'm quite clear
about how the use the tag.

I was hoping this thread would die on its own but now I'm getting worried
it will live on for another month.

Sorry for the rant.

Regards,
Dave
